ARMORED LINER FOR Trans.

Specification of Letters Patent.

Patented June 21, 1921.

Application filed September 17, 1920. Serial No. 410,892.

nois, have invented certain new and useful Improvements in Armored Liners for Tires; and lV do hereby declare the following to `be a full, clear, and exact description of the 1nvention, such as will enable others skilled in the art to which it appertainsto makeand use the same. Y

This invention relates to new Aand useful improvements in Yarmored liners lfor tires of the character employing inner andv outer armor elements and each consisting of a plurality of strips arrangedtransversely and has for itsprimary object the provisionof longitudinally extending tongues formed 1ntegrally with the strips for retaining the latter in their proper relation to each other and within the liner and also to facilitate the handling and assembling of the strips in the liner.A

Another object of this invention is `the provision of corrugations ink each strip adapted to prevent a strip when broken from overlapping itself orlanother strip or from moving or shifting transversely and longitudinally of the liner.

A further object of this invention is the provision of an armored liner for tires of the above stated character, which will be simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination2 and arrangement of parts aswill be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanylng drawings, in which- Figure 1 is a fragmentary perspective view illustrating a tire with a liner positioned therein and constructed in accordance with my invention,

Fig. 2 is a fragmentary plan view illustrating one of the armor elements,

Fig. 3 is a fragmentar transverse sectional view drawn on an en arged scale illustrating the corrugations ofthe strips and the embedding of the same in a pad or body, and v M Fig. 4 is a fragmentary plan view, illustrating a modified form of my invention.

Referring in detail to the drawings, the numeral l indicates an armored liner adapted to be positioned within a shoe or tire 2`A for rotectinfr the usual inner tube avainst 4 an D punctures and blow-outs. The liner l includes 1a pad or body which is constructed from plies of crude rubber 3 and rubberized `fabric V4. `Preferably three plies of crude rubber are used, one ply is placed between inner and outerV armor elements 5 and the other two plies of 'cruderubber are positioned overrsaid inner and outer armor elements, so that the armor elements are nested in a comparatively soft bed or cushion which will permit them to readily flex when in use. The plies of crude rubber 3 are covered by the plies of rubberized fabric 4 and the plies 3 and 4 vary in widths so that when said plies are subjected to a vulcanizing process they will mold into a pad with comparatively thin edges as shown in Fig. l, and the plies of fabric may be of any desired number so as to afford kthe desired strength tothe liner. The pad is comparatively thick at its portion which underlies the tread of the tire 2 and inl which the armor elements are embedded and gradually tapers toward its i longitudinal edges so as not to terminate abruptly in the tire and thereby permit the inner tube to rest smoothly thereon without any dangerof chafing or injuring the latter.

The armor elements 5 are constructed preferably from high grade steel but any other material may be used, that is suitable for the purpose and each includes relatively spaced and transversely disposed stripsconnected together at their medial portions by integra-l tongues 7 thatextend longitudinally. The tongues 7 are of a decreased width at their medial portions so that if the tongues are broken during the use of the device they will break at their medial portions and remain attached to the strips, thereby obviating loose particles which would be liable to work through the pad and puncture the inner tube.` Each strip is provided with corrugationsthat extend from each end thereof toward the medial portions andterminate adjacent to the medial portions. The liability of the Strips breaking during Vthe spaces betweeuthe strips of the other armorfelement so as to formv a continuous armor for theinner tube. .The ends ot' the strips of the inner' and outer armor elements are arranged in alinement witheach other as shown in Fig. 3 or one ofthe armor ele-Y ments may be shifted transversely of the other armor element as shown in Fig. t it desired.

, The armor elements being constructed of a plurality of strips permit them to readily ex during the expansion and contraction of the Vtire` and by having the strips connected vby tongues` permit of them to be more readily handled and assembledin the` pad as well as aiding in retaining the strips inl their proper relation with each other when embedded in the pad. Y

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed. Y v

points adjacentV their medial portions,

Having thus described my invention what I claim is l 1. An armor for pneumatic tiresl comprising apluralityV of elongatedr narrow.. plates of elastic metal, and narrow tongues con- 1necting the'plates in strip formation with their longitudinal sides in relatively spaced y relation and adapted to hold sai-dplates in Y spaced relation when the armor is curved transversely.

2. An armor for pneumatic tires comprising a plurality of elongated narrow plates of elastic metal, corrugationsformed in said plates and.V ext-ending 'from their Y ends to and tongues Vconnecting thev plates in strip fformation with their longitudinal sides in relatively spaced relation.' j

3. An armor for pneumatic tires comprising a plurality of elongatedfvnarrow plates of elastic metal,,corrugationsfformed in said plates and extending from theiry ends *toV points adj acentV theirmedial portions,

said corrugations extending above and below the plane Vot' saidplates, Vand tongues connecting the Y medial portions of said plates and having their medial portions def creased in rwidth so that when broken they will break` at their medial portions and remain attached to the plates.

In testimony whereofv I affix my sig-natureVV in presence of two witnesses. Y
